fatigue analysis using ABAQUS

I am new ABAQUS user, i want to learn ABAQUS for the analyis of failure of material i.e fracture, creep and fatigue. my aim is get analysis of a fatigue analysis of rotating and bending welded alloy. can you please help me in doing this analysis on ABAQUS.........please send any fatigue tutorial of ABAQUS..


ABAQUS/CAE simulating surface wave

hello, I am an MTech NDT student. I would like to know how to create a node set for transmitting and recieving ultrasonic surface wave through a 2D deformable sheet and through a 3D bar, using ABAQUS/CAE

Journal Club Theme of April 2012: Phononics: Structural Dynamics of Materials

Engineering structures are made out of materials and as such there is a natural hierarchy in which a material’s intrinsic properties contribute to shaping up the structure’s response. It is possible however to reverse this hierarchy and engineer materials that are made out of structures. In this case, the intrinsic properties of a material are shaped by the structural response. Such a configuration can only be realized with a repeated structure, forming an array of identical unit cells.

PhD Studentship in Advanced Tomographic Microscopy for Damage Modelling in Steels

Imperial College London
Department of Mechanical Engineering

Applications are invited for a research studentship in the field of Advanced Tomographic Microscopy for Damage Modelling in Steels, leading to the award of a PhD degree.  The post is supported by a bursary and fees (at the UK/EU student rate) provided by EPSRC.  The studentship is for 3.5 years from October 2011 (or to start soon after) and is available for UK and EU candidates meeting the Research Council criterion of having been resident in the UK for the previous three years. The student will benefit from collaboration with Tata Steel, a leading global metal processing company. Tata Steel will also provide a bursary top-up; the total bursary will be approximately £19,000 per year tax-free. The student will also benefit from use of the Diamond Light Source, and interactions with scientists at both the Diamond facility and University of Manchester.

Please read attached advert for further details.

Spectacular torsional-flexural autovibrations of a Volga bridge

The autovibrations of the bridge over Volga river in the city of Volgograd(Russia) were filmed (not by me) today on 05/21/2010. The amplitude reachedabout 1 m. The bridge opening was just six months ago...

Apparently, either the bridge frame drag was too high or torsional stiffness / damping too low.

[Webcast] Nuclear Power - from Last Gasp to Second Wind

This lecture reviews the tumultuous changes taking place in the nuclear industry; from its enthusiastic beginnings, through the darker days and on to the current resurgence. It explores the future of nuclear power as a major solution to energy security and climate change issues.


The History of Another Dimension - 50 Years of Bentley's V8 Engine

Dr Ulrich Eichhorn's lecture covers the original design and development of the Bentley V8 engine, from its introduction in 1959, in their S2 model, through to its present day form in the newly launched Bentley Brooklands coupe.

With contributions from several senior figures involved with the engine's creation and evolution over the last 50 years, the talk will describe how a well thought out concept and its careful execution have carried the design through to 2009, while other contemporaries have long since fallen by the wayside.

How to post a presentation?

Giving presentations at conferences or seminar series is a vital part of a researcher's professional life.  Listening to others' presentations is also one of the best ways to stay current with the frontier of a research field. While the audience in conference/seminar room is often limited, a presentation posted online can be virtually viewed by any interested audience. At iMechanica, users have started to post their presentation slides, quite often as the attachments of a post briefing the presentation.  Such a way is simple and effective, but may not be the best way for everyone for the following reasons:

Collapse of the Tacoma Narrows Bridge, 7 November 1940

In today's class of complex analysis, my co-instructor Scott Norris was lecturing on resonance.  He mentioned a YouTube video of the Tacoma Narrows Bridge.  Also instructive is the entry of the bridge on Wikipedia

Everything is miscellaneous (Video)

While preparing a talk on iMechanica , I came across the following video "Information R/evolution" by Michael Wesch, an assistant professor of anthropology at Kansas State University.  This thought provoking video echoes a recent comment on "The future of knowledge?"

Enjoy!
